// Presentation :

//   PclZip is a PHP library that manage ZIP archives.

//   So far tests show that archives generated by PclZip are readable by

//   WinZip application and other tools.

//

// Description :

//   See readme.txt and http://www.phpconcept.net

//

// Warning :

//   This library and the associated files are non commercial, non professional

//   work.

//   It should not have unexpected results. However if any damage is caused by

//   this software the author can not be responsible.

  // ----- Constants

  // ----- File list separator

  // In version 1.x of PclZip, the separator for file list is a space

  // (which is not a very smart choice, specifically for windows paths !).

  // A better separator should be a comma (,). This constant gives you the

  // abilty to change that.

  // However notice that changing this value, may have impact on existing

  // scripts, using space separated filenames.

  // Recommanded values for compatibility with older versions :

  //define( 'PCLZIP_SEPARATOR', ' ' );

  // Recommanded values for smart separation of filenames.

  // ----- Error configuration

  // 0 : PclZip Class integrated error handling

  // 1 : PclError external library error handling. By enabling this

  //     you must ensure that you have included PclError library.

  // [2,...] : reserved for futur use

  // ----- Optional static temporary directory

  //       By default temporary files are generated in the script current

  //       - MUST BE terminated by a '/'.

  // Description :

  //   This method supports two different synopsis. The first one is historical.

  //   This method creates a Zip Archive. The Zip file is created in the

  //   filesystem. The files and directories indicated in $p_filelist

  //   are added in the archive. See the parameters description for the

  //   supported format of $p_filelist.

  //   When a directory is in the list, the directory and its content is added

  //   in the archive.

  //   In this synopsis, the function takes an optional variable list of

  //   options. See bellow the supported options.

  // Parameters :

  //   $p_filelist : An array containing file or directory names, or

  //                 a string containing one filename or one directory name, or

  //                 a string containing a list of filenames and/or directory

  //                 names separated by spaces.

  //   $p_add_dir : A path to add before the real path of the archived file,

  //                in order to have it memorized in the archive.

  //   $p_remove_dir : A path to remove from the real path of the file to archive,

  //                   in order to have a shorter path memorized in the archive.

  //                   When $p_add_dir and $p_remove_dir are set, $p_remove_dir

  //                   is removed first, before $p_add_dir is added.
